Study Notes
Hydrogen
- Unique element not part of any group on the periodic table
- Has 1 valence electron, making it very reactive
- Exists as a gas at room temperature, colorless and odorless
Alkali Metals
- Group 1 elements with 1 valence electron
- Characterized by a silver color and low density
- Extremely reactive, especially with Group 17, forming a +1 charge
Alkali Earth Metals
- Group 2, featuring 2 valence electrons
- Highly reactive and good conductors of electricity
- Typically bond with Group 16 elements to achieve a +2 charge
Transition Metals
- Comprise Groups 3 through 12 of the periodic table
- Conductivity increases from left to right, while reactivity tends to decrease
- Includes the Lanthanide and Actinide series with varying valence electrons
Boron Group
- Group 13, named after its top element, boron
- Consists of one metalloid and the remainder as metals
- Contains 3 valence electrons
Carbon Group
- Group 14, named after carbon, the top element
- Contains 4 valence electrons, one non-metal, two metalloids, and remaining metals
Nitrogen Group
- Group 15, named after nitrogen, containing 5 valence electrons
- Consists of two non-metals, two metalloids, and one metal
Oxygen Group
- Group 16, named after oxygen, featuring 6 valence electrons
- Composed of three non-metals, one metalloid, and one metal
Halogens
- Group 17 elements having 7 valence electrons, all of which are non-metals
- Poor conductors of heat and electricity, highly reactive
- Tend to bond with Group 1 to form a -1 charge
Noble Gases
- Group 18 elements that are inert and not reactive
- Characterized by a full valence shell, resulting in no bonding with other elements
Metals
- Majority of elements fall into this class, found on the left side of the periodic table
- Features include being shiny, good conductors, malleable, and ductile
- Most are solid at room temperature, except mercury, which is liquid
Nonmetals
- Located on the right side of the periodic table, they lack malleability and ductility
- Poor conductors of heat and electricity; about half are gases at room temperature
Metalloids
- Positioned along a zigzag line, exhibiting properties of both metals and nonmetals
- Comprises 8 elements in total with mixed characteristics
Isotope
- Variants of an element differing in neutron count
- Leads to atoms of the same element possessing different atomic masses
Cation
- A positively charged element formed when there are fewer electrons than protons
Anion
- A negatively charged element created when there are more electrons than protons
